IMPRQVED'WRITING AND DRAWING-DESK.

To ALL WHOM Ir MAY coNcE'RN; Y p

Be it known that I, WILLIAM W. Lnvssine, of the city, county, and State of NewYork, have `invented a new and improved Writing and Drawing-Desk; ,and I do hereby'declare that the following isa full, clear, andexact description thereof, which will enableothers skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification. i

Figures'l and 2y represent front elevations of my. iinproyed desk. Figure 3 is a vertical transverse section ofthe same. i Figure 4 is a rear elevation ofthe same. Similar letters of reference indicate corresponding parts.

This invention relates to al new desk, which is provided with slates, blackboard, and transparent groundglass plates, in suchrmanner that it will be convenient `for teachers, artists, and business men.

The invention consistsi i lFirst, in arranging a. slate upon the top plate of the tabl calculating purposes, and for memoranda, may be provided.

e-part of the desk,sothat la convenient table for Second, in arranging on the front of the folding lid, a removable plate of ground glass, which can either be used for writing upon, or behind which designs can b e placed to he copied from.

Third, in arranging, on the backof the desk, a stationary blackboard, which can -be used when the desk is turned round.

' Fourth, in so arranging a. drawer under the whole table part of the desk, that it can be halfv drawn out in' front, and half in rear, a partition being arrangedacross it; thereby adrawer' is provided for cach face of the desk, and still, in construction, both are but one drawer. vMaterial and labor are thus saved to a' considerable extent.

A, in the drawing, represents the table part of a desk, of suitable size and form, and made of suitable material. It is supported by legs B, or their equivalents.

l C is the top of the desk, put upon the table. It has a folding lid, D, by which it is closed in front, as in. iig. 3. This lid, when folded down, as sho'wn in iig. 2, rests upon and covers the front part of the table, and forms an inclined plate to write upon. 1

The inkstand a, and pen-racks b, may be secured to the lower part of the lid D, as shown in figs. 2 and 8, or may be placed into a shelf of thc'top, C. I u l In the table is arranged a drawer or drawers, E, extending clear across from front to back.

` This drawer is, about in the middle, divided in two by means of a partition, c, and under'this partition projects from the bottom of the drawer, a stop Vor stops, d, preventing the drawer from being drawn out at either 'side further than to the partition c. i

In this manner a double drawer is produced, which can be partly drawn out from front and rear of the desk:

Still that part which is in front can never bcireached from the rear, and that which is inrear could not be got at from the front. I v Y f The rear halt` of the drawer is thus in some respects a secret drawer, as parties unacquainted'with the constructionwould not readily suspect the extension, after having pulled the drawer out infront.

The drawer can be closed at either end by a lock, or by a suitablestop, e. i

The top plate F of the table Avis inclined as far as it is in front, and clear of the-top, C.

In it is held n. countersunk slate, or equivalent m'aterial, G, upon which exercises in writing, or calculations,

can be made'. l

The front face of the lidD is provided with projecting ribs ff, on top andv bottom, and with an abutting rib, g', at one end, between which a sliding frame, I, can be inserted. This frame serves to hold a removable ground-glass plate, J, which can be used to write upon, as in iig. 1, o r behind which a suitable design or print can be placed, to be in a convenient place for copying. The plate J may, however, be secured. to the lid in any other suitable manner.

When thelidis folded down, as shownrin iig. 8, the shelvesK inthe top of the deskvfill he displayed and thrown open, and the upper surface of the lid will form the top of thel table.

L is a blackboard, formed on the back of the desk, of suitable material. It eari be used in schools and other' places in the same manner-as ordinary blaekboards, and will be seen by turning the desk around, as in g. 4.

The desk thus constructed will be very convenient in schools and colleges of all kinds, and will be very convenient to teachers, as well as to students, and also suitable for oice and household-desks.

Y Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-' 1. The deseribed arrangement ofthe slate Gr in the part F, the sliding frame and removable ground-glass plate J in the hinged portion D ofthe desk, the blackboard L, on the back of the upper' desk, andthe drawer E, having the partition c and stop or stops d, all constructed to operate in the manner and for the purposes substantially as herein set'i'orth 'and'showm Y l 2. The within-described combination of writing-desk, blackboard, drawing-slate, and writing-slate, as set forth.

The above speecation of my invention signed by me, this 9th day of June, 1868.

' WM. W. LEVERING.
